Specification of Letters Patent.

Patented July 14, 1908.

Application filed September 23, 1907. Serial No. 394,064.

To all whom it may concern:

Be it known that I, LEVI J. LENNoX, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Folding Beds, of which the following is a specification, refer ence being had therein to the accompanying drawings.

This invention relates to beds and to improvements in folding beds especially adapt- 1ng them for use in hospitals and for invalids.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a plan view of a bed embodying features of the invention. Fig. 2 is a view in side elevation, partially broken away, showing the bed in normal position. Fig. 3 is an end view of the bed. Fig. 4 is a view in side elevation of the bed in a folded position. Fig. 5 is an end View in detail of the bed-spring frame. Fig. 6 is a view in detail on line 0ca; of Fig. 5 of a link and roller. Fig. 7 is a view in detail of a swing shelf on the bed. Fig. 8 is a view in detail of a pivot block for the shelf. Fig. 9 is a view in detail of a side bracket. Fig. 10 is a view in detail of a section upper hinge or pivot joint.

As shown herein, a rectangular main-frame preferably constructed of side angle irons 1 and end angles 2 properly connected at-the corners, is pivoted off center by any suitable means, preferably ball tenons 3 detachably interlocking with sockets 4, to two-part end boards whose movable sections are adapted to fold inwardly against the frame when the latter is in upright position. In the preferred form herein illustrated, the stationary sections of the boards each consist of a tubular corner post 5 inbent and suitably connected at its u per end as by a butt weld joint to a tubu ar upright 6, a cross brace 7 at the regulation height of a bed rail completing the frame. A stay rail 8 has end tenons 9 of any conventional type ordinarily used for side rails, detachably interlocking with mortise blocks 10 near the lower ends of the uprights 6 out of vertical alinement with the sockets 4, so that the main-frame and stay rail maintain these sections in proper relation. sist of a corner post ll'bent to correspond to the opposite post 5, a cross rail. 12 whose inner end is shouldered and halved to the inner The movable sections each con end of the cross brace 7 to form an inwardly breaking hinge 13 of the rule-joint type, and a standard 14 which is stepped on the rail 12 in symmetrical relation to the upright 6, and

is bent over and suitably pivoted to the upg per end of the upright in axial alinement therewith, preferably by dropping over a pintle 15 inserted on the upright.

The projecting ends of a clamping rod 16 longitudinally movable in guide apertures in the end angle bars 2 beneath the horizontal flange of the main-frame enter segmental slots 17 in hanging brackets 18 secured on the outer posts of the head and foot boards when the latter are extended. A head 19 on one end of the rod and a washer 20 on the other end may be forced toward each other by a suitable hand lever 21 which cams against I the washer when depressed, or is otherwise adapted to clamp the washer and head against the brackets. The contacting surfaces of the brackets, rod head and washer may be serrated or notched if desired, and a seat 22 for the head and washer may be formed in each bracket for accurately locking the main-frame in horizontal position. A flange 23 on the bracket acts as a shield for the head or washer. The rod is released when the hand lever 21 is loosened, by a spring 24 in compression between the end angle iron near the lever 21 and a block 25 secured on the rod whose movement to- Ward the frame center is limitedbya stop 26 on the under side of the side angle iron. When the handle is of the form herein indicated, having a flattened rounded end 27 eccentrically centered by a pin 28 in a slot in the end of the bar, the block 25 may be adapted to bear laterally against the side angle iron and hold the rod against rotating with the handle in convenient operating position.

A rectangular mattress or spring frame of side rails 29 preferably of angle iron, secured together by a head rail 30 and a foot rail 31, likewise preferably of angle iron, is pivoted at the foot to the main-frame by bolts 32 or the like passing through the depending flanges of the side rails and of the side angle bars 1, which the side rails overlap closely when closed thereon. The lower horizontal flange of the head rail 30 rests on a pair of friction rolls 33 journaled on studs 34 secured to arms 35 which are pivoted at their lower ends to the main-frame and articulated to move in parallel relation by a horizontal link 36 having an outturned end or handle 37 near the front side of the bed. By pulling the handle 37 toward the front of the bed until the arm rolls 33 are past the vertical line of the arm pivots and the arms engage a suitable stop 38 the mattress spring frame may be longitudinally tilted. A spring clip 39 on the side rail hooks over the main-frame when the upper frame is in its normally horizontal position.

A shelf -40 is pivoted to a pivot block 41 which slides on the clamping rod 16 and is held from rotation by engaging with the adjacent side angle. The shelf is adapted to turn completely under the frame, a forked be readily taken apart for shipping or clean Obviously the head and foot boards mg. may be of any ornamental design preferred.

One feature of the invention is the compactness of the frame, the superposed side angles of both frames closing by each other and the end angles lying back to back. Another feature is the grouping of the manipulating means at the front side of the bed so that the bed may be secured in the position 7 desired without reaching over or otherwise disturbing an occupant. At the same time the clamping rod and head raising lever do not project beyond the bed proper, and are practically concealed.

Obviously changes in the details of construction may be made without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim as my invention is 1. A folding bed comprising two part end boards each consisting of a stationary section and a movable section hinged thereto to swing in a horizontal plane, a main-frame pivotally supported at each end on the stationary sections and adapted to be secured in laterally tilted position to the movable sections when they .are extended, and a spring frame longitudinally tiltable on the main-frame.

2.
